Many many things can cause a high idle. I don't think bucking could really be caused by bad O2 sensors. Is your check engine light on?

High idle is likely a vacuum leak check hoses and gaskets O2 sensor has to do with. Your air fuel mixture I have no wires going to my O2s yet and I idle around 750-800
